[0035] Please refer to Figures 1-6 , the present invention provides a technical solution: a rotatable vacuum cleaner mobile accessory tray structure, including: a mobile bracket 1, a base 2 and a turntable 3. There are universal wheels 4 under the mobile bracket 1. There is also a storage groove 11 on the bottom surface of the mobile bracket 1. There is a support foot 12 in the storage groove 11. There is a threaded rod 121 on the back of the support foot 12. The threaded rod 121 is threadedly connected to the bottom surface of the storage groove 11. There is a bearing bracket 21 in the base 2. There is a bearing 22 in the bearing bracket 21. The base 2 is fixedly installed on the mobile bracket 1. There is a connecting column 31 on the back of the turntable 3 corresponding to the storage groove 11 in position. The threaded rod 121 passes through the bottom surface of the storage groove 11 and is threadedly connected to the connecting column 31. There is an accessory storage groove 32 on the surface of the turntable 3. One end of a rotating shaft 5 is fixedly connected to the inner ring of the bearing 22, and the opposite end passes through the bottom surface of the accessory storage groove 32. There is a pin 6 at the end of the rotating shaft 5. The pin 6 is perpendicular to the axis of the rotating shaft 5. The pin 6 passes through the rotating shaft 5. The end of the pin 6 contacts the bottom surface of the accessory storage groove 32. The rotating shaft 5 is connected to the turntable 3 through the pin 6 at the end. The turntable 3 is rotatably installed on the mobile bracket 1 through the rotating shaft 5.

[0036] There is a groove 122 on the bottom surface of the support foot 12. The groove 122 is used to facilitate the rotation of the support foot 12, and the principle is similar to that of an internal hexagonal bolt.

[0037] There are several profiling positioning blocks 321 on the bottom surface of the accessory storage groove 32. The vacuum cleaner accessory 7 is plugged on the profiling positioning blocks 321, which is convenient for taking and placing the vacuum cleaner accessory 7.

[0038] A gasket 51 is sleeved on the rotating shaft 5. The gasket 51 contacts the bottom surface of the accessory storage groove 32. The end of the bolt 6 extends above the gasket 51. The gasket 51 replaces the bottom surface of the accessory storage groove 32 and contacts the rotating shaft 5, reducing the friction between the rotating shaft 5 and the turntable 3 and making the rotation smoother.

[0039] Four universal wheels 4 are circumferentially and equidistantly arranged on the bottom surface of the moving bracket 1, and four support feet 12 are circumferentially and equidistantly arranged on the bottom surface of the moving bracket 1. The universal wheels 4 and the support feet 12 are arranged at intervals. On the one hand, it is convenient to move the accessory tray, and on the other hand, the support feet 12 can stably support the accessory tray.

[0040] Working principle: When the accessory tray is in use, the vacuum cleaner accessory 7 is placed on the turntable 3, and the accessory tray is placed on a placement platform such as the ground. In the normal state, the threaded rod 121 on the back of the support foot 12 on the moving bracket 1 passes through the bottom surface of the storage groove 11 and is threadedly connected to the connecting column 31. At this time, the bottom of the support foot 12 does not contact the ground, while the spherical bottom of the universal wheel 4 contacts the ground. At this time, the accessory tray can move freely and rotate 360 degrees as a whole, facilitating the picking and placing of the vacuum cleaner accessory 7. The threaded rod 121 is threadedly connected to the connecting column 31 of the turntable 3 to prevent the turntable 3 from rotating during the movement of the accessory tray.

[0041] In order to lock the position of the accessory tray and prevent the accessory tray from moving, the support foot 12 can be rotated out of the storage groove 11 so that the bottom of the support foot 12 contacts the ground, while the spherical bottom of the universal wheel 4 is separated from the ground, preventing the accessory tray from moving randomly. At this time, the threaded rod 121 rotates downward with the support foot 12 and disengages from the connecting column 31 of the turntable 3. The threaded rod 121 is still connected to the bottom surface of the storage groove 11. In this way, the turntable 3 can rotate through the rotating shaft 5, changing the relative position with the moving bracket 1, so that the turntable 3 can still rotate 360° to facilitate the picking and placing of the vacuum cleaner accessory 7 without the need to move the accessory tray.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
